i've spent a good number of hours RTFMs, trying to make the best of a bad
situtaion: userland natd instead of kernel-space nat.
the only practical advice i found was to increase the maxusers kernel
option - we're already at 1024 (with plenty of ram to support it). other
advice was to have a streamlined ipfw list and i think mine is.
the problem is that high network traffic with natd means that the CPU
spends its time doing nat and not paying much attention to anything else.
re-niceing it just means lower thoughput.
any advice on squeezing more out of natd?
* natd spawning other natds?
* combinations of command line options?
* more kernel parameter tweaking?
thanks
